“…The methods of reducing emissions of harmful substances by influencing the working process include the improvement of the fuel supply process [3,4,5]. This is due to the fact that the processes of fuel supply, atomization and mixture formation predetermine the nature of the subsequent combustion process and, as a result, the mentioned environmental indicators of a diesel engine.…”

The toxicity indicators of exhaust gases of a diesel engine largely depend on the quality of the fuel supply process. The possibility of a significant improvement in the toxicity of the exhaust gases of a diesel engine by optimizing the phase of the start of fuel supply - the fuel injection advance angle is shown. To assess the influence of the fuel injection advance angle on the dynamic performance of the engine and the toxicity of exhaust gases, a mathematical model of the engine has been developed. The model contains differential equations for the main elements of the combined engine - its piston part, turbocharger, in take and exhaust pipelines. These equations include polynomial dependences of the main engine parameters on its operating parameters. The object of research was diesel type D-245 (4 ChN 11/12.5) produced by the Minsk Motor Plant. Calculations of the acceleration of the engine with a variable fuel injection advance angle have been carried out. The influence of the law of regulation of the advance angle of fuel injection on the duration of the transient process and emissions of normalized toxic components is determined.

“…At the present stage of engine building development, the main consumer qualities of internal combustion engines remain their fuel efficiency and exhaust gas toxicity [1,2,3]. The simplest and most effective means of influencing the diesel workflow in order to improve fuel efficiency and exhaust toxicity is to improve the fuel supply process [4,5,6]. In order to achieve the required economic and environmental performance of the engine, high flexibility and quality of fuel supply management are required in all modes of diesel operation, which is shown in a number of studies [7,8,9].…”

The quality of the fuel supply process is the main criterion for ensuring the required indicators of efficiency and environmental friendliness of a diesel locomotive. The electronic control system of the ESUVT.01 type for D50 type diesel (6 CHN 31.8/33) for fuel supply control is produced by JSC Penzadizelmash developed in LLC PPP Dieselavtomatika (Saratov) is presented. Optimizing the phase of the beginning of fuel supply – the advance angle of fuel injection (AAFI) shows the possibility of a significant improvement in fuel efficiency and toxicity of diesel exhaust gases. To assess the effect of the AAFI on the diesel locomotive performance, its experimental studies were carried out. The object of bench tests was a diesel generator set of type 1-PDG4D with the specified diesel and with a traction generator MPT-84/39. During the tests, the dependencies of diesel indicators on the AAFI were obtained. The necessity of optimizing the values of the AAFI in accordance with the engine operating mode is confirmed. Optimized values of the AAFI are obtained in the modes of diesel characteristics. The toxicity indicators of diesel exhaust gases and fuel efficiency with optimized characteristics of the AAFI are determined.
